JOHN AWHERRY, OF NEW ORLEANS, LOUISIANA, ASSIGNO'R T0 UNDERWOOD TYPE- WBITER COMPANY, OF YORK, N. Y., A CORPORATION OF DELAWARE 'rvrnwm'rmo macnnvn Application filed July 7,

To all whom it may concern:

Be it known that I, JOHN A. WHERRY, a citizen of the United States, residing in New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Typewrit ing Machines, of which the following is a specification.

The present invention relates to the art- 'of so-called continuous billing in typewriting machines; that is to say, to the typing of entries on sheets fed through the machine in a continuous chain, as, for instance, for the issuance to many individuals of statements or notices, alike as to form.

Heretofore 'a single continuoussheet or web, having the forms repeated thereon, or several of such webs, superposed for interleavement with carbons, have been fed, from supply rolls orpackages, to the platen, thereafter to have the individual forms cut therefrom. An object of the present invention is the provision of means whereby, as the work progresses, the forms may be separately inserted into the machine and there linked with the preceding forms for the feed thereof through the'machine; thus relieving the machine and its carriage of an mechanism involved in feeding and guiding a continuous form-web from a roll, or the like, to the laten.

Bills and other orms are commonly provided' with a detachable stub on which is duplicated a portion of the entry; such stubs being used as receipts or kept by the maker.

An object of the invention is the provision of means whereby individual forms having such stubs may be fed in a chain through the machine, and whereby the duplicate entry on. the stub may be made simultaneously with its original on the other part of the form; thus saving the time and trouble of making the same entry in different column-positions of the platen and of moving the carriage from one such position to another.

In connection with the foregoing, a fea-" ture of the invention isthe provision of a carbon-belt on which the individual forms are placed, one after the other, the form being folded around the same; so that the carbon while serving as the carrier, also effects the duplication on the stub.-

1922. Serial no. 573,310.

An object of the invention is a shaping or cutting of the individual forms at one edge thereof, such that, when the. edge-of a form, being positioned on the belt, is set against the opposing edge .of the preceding form, it will be held or guarded by-that preceding. form for passage as a link in the formchain through the machine. As hereinafter shown, by cutting the forms on the line of the stub-fold, and more particularly, by

the belt, for aligning the side margins of the forms, and for maintaining suchalignment, as to each form, until by movement of the belt the form is gripped on the platen.

A further feature of the invention is the provision of means for successively discharging the typed forms from the belt. In the preferred form of the invention, such discharging means consists of a stationary finger, projecting-into the path of the bights of the forms, and so directed or shaped as to cam the forms of! of the belt;v or at least to cause the forms to move laterally" outward on the belt until the weight of the stubbed ends thereof cause the same successively to fall from the-belt. v

An object of the invention is the provision of means whereby individual forms may be fed downward and around the platen from the front thereof, and the writings thereon be duplicated in condensed form on a talley-sheet fed in the opposite direction; and'more particularly, of means whereby such feed of the forms may be effected by movement of the platen independentlv of a line-space mechanism which is operable, on-

that, by inserting two of the belts in superposed position between the folds of the.

as a printing medium; and of means for changing the setting of a belt between effective and ineffective positions. I

Commonly, in this art, the desired entry is made on a single line; and thus the speed with which the work can be turned out depends largely upon the movements involved in feeding the forms successively to the printing line, and in thereafter discharging the same from the machine. From the foregoing description, it will be seen that the number of manual operations involved in continuous billing according to the present invention, is reduced to a minimum. Except for the placement of the forms on the carbon, there is no manual movement of the carbons with respect to the forms. There is no cutting of the leading typed form from those which follow it: the discharge of the typed forms is automatic. No shift of the platen or of the feeding devices, to release the forms from the carbons' or tally-sheet,

is required after one form is typed and before another form is in printing position. The feed of the tally-sheet is automatic. The feed of the forms is a front feed, thus "further. vconveniencing the operator. No shift of the carriage from one to another column-position, for writing on the stub, is involved. All is conducive: to speed and ease of operation.

Other features and advantages will hereinafter appear.

A platen 10 is fast to a shaft 11, journaled in the end plates 12 'of the platen-frame. Also fast on the shaft 11 is a hand-wheel 13, by means of which the platen may be turned in feeding the individual work-pieces to the printing position. The machine is also equipped with line-space mechanism. In using the machine for the purposes of the present invention, however, the line-space mechanism is disconnected from the platen and is only employed, as will hereinafter be noted, for effecting a line-space-feed of the tally-sheet. The line-space mechanism here employed is that shown and described in detail in United States Patent, to Helmond, No. 1,150,366, dated August 17 1915, to which reference is made for an understand ing theerof in detail. Briefly, it comprises a line-space-wheel 14, revolubly mounted on the platen-axle 11 and actuable by means of a pawl 15 on a slide 16, carried by the lefthand frame-piece 12. The slide. 16 is moved backward by the carriage-return-lever, as in the standard Underwood typewriting machine, to cause the pawl 15 to turn the linespace-wheel 14, and is returned to normal position by a spring (not shown). [Fast to the line-space-wheel 14 is a'drum 18, acting as one element of a clutch, the other element of which. not shown, is contained within the drum 18 and is fast to the axle 11. When the two clutch-members are locked together, the line-space-wheel .will turn the platen. For locking and unlocking the clutch-members, there is provided a tapered stud or cam piece 19, shiftable longitudinally on the platen-axle, by means of pins 20, carrying a finger-piece 21. Movement of the finger-piece 21 to the right locks the 'line space-wheel 14 to the platen-axle. In mtting the machine for the :present invention, however, the finger-piece 21 is moved to the left, to the positionshown in Figure 1, in

which the'platen is free of the line-space mechanism.

For supporting the carbon-pulleys and certain other features of the resent invention, there is a frame comprislng side plates 26; A shaft 22, mounted in the end plates 12 of the platen-frame, passes through, and supports, the plates 26. Set-screws passing through bosses 23 on the plates 26 serve to fix' the plates on the shaft 22. The plates 26, in addition to being supported on the shaft 22, whichis a fixed shaft,-are also provided at their lower ends with rollers 27, by means of which they ride and are, in part, supported by the platen. Each of the plates or brackets 26 has, at its upper end. an car 28, offset thereon and provided with a pin 29. When the brackets 26 have been fixed in place upon'the shaft 22, they are sprung toward each other, to'permi-t a cross-tie or bar 30- to be locked thereto, by means of bayonet-joint connections which slots 31 in the bar.30 form with the pins 29. Upon release of the brackets 26, they spring to their normal setting, causing the bar to be securely held thereby. The bar 30 thus serves as a cross-brace for a frame of which the brackets26 form a part.

The frame. which immediately carries the carbon-pulleys is supported by the brackets 26. This latter frame comprises a pair of uprights 32, secured by screws 33 at the r lowerends to the brackets 26. Near their upper ends, the uprights 32 are connected and braced by a bar 34, having ears 35, secured by rivets or'screws 36to the uprights. Above the bar 34, the uprights are extended and have journeled therein a shaft 37, to which a pulley 38 is made fast, by means of a set-screw 39. The frame, of which the uprights 32 are elements, also comprises bars 40, secured to the uprights 32 by the rivets 36 and extending therefrom rearward, one on each side of the frame. In the rear ends of the bars is journaled a shaft 41,'to which is made fast another pulley 42. Secured to each of the bars 40, intermediate the ends thereof, by means of rivets 43, 1s a I downward and forward extending arm 44.

The arms 44, at their lower ends, carry a plate 45 (see Figures 2 and 3). In Figure 3, the ri ht-hand arm 44 is shown as having an 0 set, to provide for an extension of the plate 45 at that side. As. shown 1n Figure 2, the upper forward edge of the plate 45 is curled at 46, to engage-and rest upon the upper beaded edge 47 of the usual paper-shelf 48. The paper-shelf 48, being supported on the platen-carriage, serves as a support for the pulley-frame on theplaten-carriage tothe rear ,of the support thereon provided by the brackets 26. p

In Figure 2, two endless carbon sheets or belts 49 and 50 are shown as led over. and downward from pulley 38, to and around the platen between the latter and the apron and paper-shelf'48, to and around the rear pulley 42, and thence upward and forward to the pulley 38. The usual front and rear ressure-feed-rolls 51 and 52 are indicated in the drawings. As shown in Figure 1, however, these rolls are beyond the edges of the carbon-belts, and, consequently, the latter, in passing around the laten, are not engaged by the feed-rolls. 11 order, however, that the carbons may snugly embrace the platen, so as to be fed around by and with the latter when the platen is turned by the hand-wheel 13, the carbon-belts are held taut. For holding the belts 49 and 50 taut, idlers 53 and 54, respectively, are provided. The idler 53 is journaled in the ends of arms 55, loosely pivoted on the shaft 37 the pulley-shaft 37. Collars 57, held by setscrews 58 to the shaft 37, hold the arms 55 and 56, and assist in holding the pulley 38, against longitudinal displacement on the shaft '37, and provide for longitudinal adjustmentof these parts on the shaft 37 A collar 59, held to the shaft 37 by a setscrew 60, holds the shaft 37 against such longitudinal displacement as might cause it to become disconnected from the framemembers 32. To assist in the feed of the carbon-belts, and in order that there may be no undue' pull. or strain thereon, by the platen, such as might tend to tear the same, a drive is provided from the platen to the pulley 38. This drive consists of a coilspring belt 61, set in an annular grooye 62 in the end of the platen and in a grooved pulley, made fast by a screw 64 to the pulley-shaft 37'. The effective diameters of the pulley 63 and of the groove 62 in the platen are the same, and the diameters of the pulley 38 and of the platen are the same, so thatthe pulley 38 is driven at the same peripheral speed as the platen as and when. the latter is turned by the handbill-forms, particularly where the bill-form-- stubs are to be inserted between two carbonbelts'- The length of the plate from to to bottom is shown as somewhat greater t an the length of the bill-form; and the plate extends down to a point near the; platen. The upper and lower edges of the plate are preferably curled, as indicated at 67, so that the carbon-belts will not. catch upon the same.

Two carbon-belts are shown so that the writing'o'n' the duplicate forms, that is to say, on'the folded stub of the individual bill-forms, may be either black or red. Ordinarily,'the belt 49 for printing on the individual bill-stubs will be a black belt: in which event the belt 50 would be a red belt. When it is desired to print the duplicates or stubs in black ink, the red belt is led, as shown in-Figure 2, fromthe pulley 38 back of the plate 65 and is available, if desired, for such use, to rint upon the tally. For guiding the red belt back of the plate 65,

the latter on its rear face. is provided with ears 68, carrying upper and lower idle pulleys 69, over which the red belt passes, and by means of which the red belt is held spaced away from the plate 65. Where the red belt is to be used for printing on the billstubs, it is passed down with the black belt in front of the plate 65.- The plate 65 is readily removable to permit it to be placed behind both belts, or, as shown'in Figure 2, to be placed between the two belts.

The manner in which the individual billforms are inserted and carried through the machine is as follows. With the belt positioned as shown in Figure 2, and the individual forms having previously been folded on the dotted line 70 (see Figure 5), the individual folded forms are passed in front of the plate 65, laterally from the righthand side, in such manner that the stub 66 thereof enters between the belt 49 and the plate For aligning the folded right-hand margin of the combined bill and stub, and for determining the position to which the same is moved over the plate in the operation of inserting the same, there is provided a flat, thin gage-finger 71, which is held by screws 71 at its upper end to the cross-tie 34, and which depends therefrom, in'front of the plate 65, to its distal end 71, "below the lower edge of the plate 65. The gage-piece 71 is spaced forward of the plate sufficiently to permit the folded stub 66 of the bill-form to be passed between the same and the plate 65. As shown in Figure 1, the gage-piece 71 is clear of the carbon-belt at the right-hand side of the latter. In inserting the bill-form, therefore, the stub 66 passes first behind the gage-piece 71 and then behind the belt, and the body-portion of the bill-form passes to the outside of both the gage-piece and the belt. When the folded bill-form has been moved until the bight thereof comes into engagement with the right-hand edge of the gage-piece, it is properly aligned and positioned for forward feed with the belt.

Thus positioned, the folded bill-form, or rather the leading one of such forms, is slid downward along the aligning member 71 until the bottom edge thereof may be engaged by the front pressure-rolls 51, and thereupon be fed with the belt and by rotation of the hand-wheel 13 to printing position. It will be noted that the length of the gage-piece 71 is sufiicient to hold the folded bill-form properly aligned until the same can be engaged by the feed-rolls.

As shown in Figure 5, the stub-portion of the individual form is cut away on a line 72, below. the upper edge 73 of the main portion 74 of the form. 'A quarter of an inch thus cut from the top of the, stub will ordinarily be suflicient for the purposes intended. The purpose of this out, as shown in Figure 7, is to permit the lower edge 75 of a succeeding form to be inserted behind the upper edge 73 of the preceding form.

--Since, in inserting the form, the same is folded around the aligning piece 71, the succeeding form inserted, as indicated, behind the upper edge of the preceding form, must come to rest and be stopped with its lower edge 75 on the upper edge 72 of the stub of the preceding form. The cutting away of the stubs on the lines 72, therefore, not only allows for an overlapping of the succeeding form by the preceding form, but.

provides a positive means for determining the amount of overlap and the proper relative position of the forms along the carbonbelt for feed through the machine. A succeeding form thus overlapped by a preceding form cannot spring out and foul any of the printing instrumentalities or guides in passing through the machine.

Withonly the black belt 49 in front of .the plate 65, the printing on both the main portion 74 and on the stub-portion66 of the form, both original and duplicate, will be in black. When printing in red on the duplicate or stub 66 is desired, and-both belts 49 and 50 are in front of the plate 65, the folded forms are so inserted that the stubs 66 lie between the under, or red, belt and the plate 65; the main-portion 74 of the form being forward of the outer or black belt. The black belt then prints only on the uncarbonized face of the red belt, and the red belt prints on the stub, and also, when desired, on the tally-sheet, presently to be described.

The stubs, set together on the belt in a continuous chain, as above described, are fed downward around the platen, and upward along and over the paper-shelf 48. This feed, as heretofore mentioned, is effected by reverse movement of the platen by the hand-wheel 13, bringing one after another of the forms to printing position. The leading edge of the leading form having passed over the rear upper edge of the paper-shelf 48, has the bight thereof engaged by'the pointed end 76'0f a finger 77, secured by screws 78 to an arm 79, depending from and forming a continuation of the right-hand frame-piece 40. The finger 77 as shown in Figure 3, is inclined outward, from front to rear, so that the point 76 thereof having been engaged in the bight of the leading form, and the leading form continuing to be pushed rearward by the belt and succeeding forms, the finger 77 earns the leading form laterally to the right, and laterally across the face of its supporting carbon-belt, until the heavier or stubcarrying side of the form causes the form to fall laterally off of the carbon-belt. On being thus disconnected and in falling from the carbon-belts, the forms may be guided by the table 45 to a suitable receptacle. The table 45 has, however, the additional function of preventing the discharged form from fouling on the mechanism at the rear of or under the'paper-shelf 48.

A tally-sheet may be used in connection with the printing of the individual forms to provide a condensed summary of the printings on the several forms. The tallysheet mechanism, shown in the drawings, is

that set forth and described in detail inaround the platen, to a take-up roll 84. For

turning the roll 84 to feed the tally-sheet and superposed carbon, there is a fast thereto a pinion 85, meshing with a pinion 86, keyed to the shaft 25. The shaft 25 is journalled for rotation in the brackets 26. Fast to the shaft 25 is a line-spacewheel 87 ,'and mounted to swing freely on the shaft is an arm 88, carrying a pawl 89 for moving the ratchet-Wheel 87; a spring, not shown, holdin the pawl against the ratchet-wheel. A link 90 connects the arm 88 to the line-space-slide 16. When, therefore, the carriage is returned by means of the line-space-lever, a linespace-movement of the shaft 25, and, with it, the pick-up roll 84, is effected. No line-space-feed of the platen is, however, effected at such times, because, as hereinbefore stated, the line-space ratchet-wheel 14 is not operatively connected to the platenaxle 11. The tally-sheet 82, therefore, has feed in the usual direction, that is to say, in a direction opposite to the direction of feed of the indivudal forms 74 and carbonbelts 49 and 50. It will be noted that the pressure-feed-rolls 51 lie outside the margins of the tally-sheet 82, so that the latter may move freely with reference to the platen.

In order that the pick-up roll or reel 84 may be turned, when desired, independently of its line-space mechanism, the gear 86 is shiftable longitudinally on the shaft 25. Normally, a coil spring 86*, bearing at one end against a collar 91, fixed on the shaft 25, and hearing at its other end against the hub 92 of the pinion 86, holds the latter in mesh with the gear 85; and, when free to do so, moves the gear 86 into mesh with the pinion 85. Supported by the tally-frameplates 80, and shiftable longitudinally therein, is a shaft 93, which bears at one end against the pinion 86 and at its other end carries a button 94. Pivotallyvmounted on the shaft 24 is a cam-plate 95, against which the button 94 is held by the action of the spring 86. This cam-plate carries a finger-piece 96, by means of which it may be rotated on the shaft 24; and the cam-plate is so shaped that, upon rotation,it acts upon the button 94 to force the shaft 93 and pinion 86 to the left, thereby disengaging the latter from the pinion 85. Movement of the finger-piece 96 in the other direction permits the pinion 86 to be returned to mesh with the pinion 85. Suitable means (not shown) is provided for holding the cam-plate 95 in a position in which the pinions 85 and 86 are disengaged from one another, so that the tally-sheet and superposed carbon may be moved any desired distance without reference to the linespace mechanism therefor. To prevent over-run of the tally-sheet supply-roll 81, and to prevent slack in the tally-sheet and superposed, carbon, there is shown in the Hart patent, above referred to, a springtension device, consisting of certain features not shown in the present drawings,

to wit, a pinion connected, to the reel 81 and meshing with another pinion on the shaft 97, which latter pinion has connected thereto a coil spring, urging the same in such direction as to hold the tally-roll taut; a slip connection being provided between such spring and the tally-roll, to permit of the necessary rotation of the latter by itsv linespace mechanism.

As shown in Figure 1 of'the drawings, printing may be effected on the tally-sheet within and out-sideof the boundaries of the carbon-sheets 49 and 50 and stub 66. The carbon 83, superposed upon the tally-sheet, provides for printing on the latter, either within or without the boundaries of the form-stub 66. For printing within the boundaries of the form-stub 66', the carbonbelt 83 might be eliminated and the car bonbelt 50 used in lieu thereof; or, for printing on the tally-sheet outside of the boundarms of the stub 66, a wider belt 50 might be used. Where both of the carbon-belts .50 and 83 used, the belt 50 prints futilely on the uncarbonized back of the belt 83 within the field ofthe stub 66.

From the foregoing, it will be seen that individual forms may be rapidly fed, bottom endfirst, in a continuous chain, downward from the front of the platen, and that the writings onsuch forms maybe condensed upon a tally-sheet fed in the reverse direction: the feed of the platen with the individual forms being effected by hand-rotation of the platen, and the feed of the tallysheet being affected by the usual line-space mechanism operated in the act of returning the carriage after the writing on each form.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

In a typewriting machine, a rotary platen, line-space mechanism therefor, means or holding a tally-sheet against the platen, pressure-rolls on the platen outside of the tall -sheet margin positions for effecting a fee of work-sheets down and aroundthe platen from the front thereof independently of the tally-sheet and outside of the tallysheet, by movement of the platen independently of the line-space mechanism, and means for effecting a feed of the tally-sheet in the opposite direction, independently of the work-sheets, b-y actuation 'of the line-space mechanism.

18. In a typewriting machine, a rotary platen, means for holding a tally-sheet against the platen, means for effecting a feed of work-sheets down to and around the platen from the front thereof indeenden-tly of the tally-sheet including a caron-belt on which the work-sheets are carried, and means for effecting a feedof the tally-sheet in the "opposite direction independently of the wor r-sheets, so that entries made on successive work-sheets will be caused to appear on the tally-sheet in the order in which the work-sheets were typed.

19. In a typewriting machine, a .rotary platen, means for holding a tally-sheet against the platen, meansfor effecting a feed of folded work-sheets down to and around the platen from the front thereof independently of the tally-sheet including a carbon-be1t on which the work-sheets are carried, a lateral guard and gage around which the folded work-sheets may be placed with one ply thereof between the carbonbelt and the tally-sheet, and means for effecting a feed of the tally-sheet in the o posite direction independently. of the worE- sheets.

20. In a typewriting-machine, a rotary platen, means for holding a tally-sheet against the platen, pressure-rolls on the p aten outside of the tally-sheet margin poa feed of work-sheets down and around t e platen from the front thereof independently of the tally-sheet,

means for effecting a feed .of the tally-sheet in the opposite direction independently of the work-sheets, a carbon-belt on which the work-sheets are carried, and a lateral guard and gage, in alignment with one of the pressure-rolls, around which the WOIk-SllGBtS' may be folded with oneply thereof between the carbon-belt and the tally-sheet.

21. A method of feeding individual formsheets through a typewriting machine, con sisting in folding one form laterally around a belt; similarly folding the next form around the belt above the first form and in underlapping relation thereto; and moving the belt downward and around the platen to bring form after form first to printing position and then around under the platen to the rear thereof. 22. A method of feeding individual formsheets through a typewriting machine, consisting in folding one form laterally around a belt; similarly folding the next form around the belt above the first form and in underlapping relation thereto; moving the belt downward and around the p platen to bring form after form first to. printing position and then around under the platen to the rear thereof; and int'er'posing a finger at a laterally outward incline in the .bight of the leading typed form, to cause such form to be'cammed off of the belt by the movement of the latter. 7

23. 'A method of preparing and feeding individual form-sheets .through a typewritingmachine, consisting in cutting the sheets at one edge thereof; folding the sheets on the line of the cut; placing the first sheet on a belt with one ply thereof on each side of the belt; similarly placing the next sheet on the belt above the other, the edges of one of the sheets being set inthe cut in the other to be interlocked therewith; and moving the belt downward and around the platen to .bring form after form first to printing poedge of the sition and then around the platento the rear thereof.

24. A method of feeding individual formsheets through a typewriting machine, consisting in folding one form laterally around a belt; similarly folding the next form around the belt above the first form with the lower edge of the last sheet under the upper receding sheet, and guarded by a cut thereln'along the fold; and moving the belt downward and around the pl ten to bring form after form ,first to prin ing position and then around under the platen to the rear'thereof.

25. In a typewriting machine for writing upon a succession of individual forms, the combination with a, revoluble platen, of a conveyor belt assing around the platen and having a frictional face to engage the forms and conduct them to the platen, a side gage for squarin the forms with relation to the platen-as t ey are placed against the belt by the operator, and means to bear against the forms to press them into frictional contact with the belt as they travel toward the laten, to prevent their slipping relatively to the belt and so to assure their being maintained in the squared condition determined by the gage.

26. In a typewriting machine for typing upon a succession of folded individual forms, a rotary platen, a carbon belt to pass with the folded forms around the platen for makin impressions upon the inner plies thereof, the arrangement being such that the folded forms can be placed upon the belt to enfold it, and a guard constructed and arranged to prevent a clumsy operator from moving his hand against the carbon belt in placing a folded form upon it, to protect the carbon belt against mutilation.
